BINDER.

Specification of Letters Patent. Patented Jan, 13, 1920,

Application filed September 11. 1917'. Serial No. 190,759.

To all whom it may concern:

Be it known that I, GEORGE G. H. FRITZ- scnn, a subject of the Emperor of Germany, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Binders, of which the following is a specification.

This invention relates to an, improvement in binders, with the object in view of providing a device in which aplurality of pamphlets or sheets may be individually and removably held therein.

Another object is to provide a binder for holding a plurality of pamphlets or sheets of unequal sizes.

Another object is to provide a binder for holding aplurality of pamphlets, each of which pamphlets is arranged to be gripped in the vertical central fold by a retaining means, thus permitting the pages of the pamphlet to lie flat when in an open position.

Another object is to provide certain improvements in the form, construction and arrangement of the elements whereby the above named and other objects may be effectively carried out.

A practical embodiment of my invention is represented in the accompanying drawings in which,

Figure 1 represents an end view of my improved binder having pamphlets or sheets of unequal size bound therein,

Fig. 9. represents a plan view of the binder open, showing the pamphlets in position therein.

Fig. 3 represents a similar view in detail, with one of the pamphlets opened at the retaining means, and

Fig. 4 represents an enlarged detail section taken in the plane of the line IVIV' of Fig. 3.

The binder comprises cover boards 1 and a back 2 secured thereto, upon which back the cover boards may swing.

A reinforcing strip 3 is secured to inside edges of the cover boards and in close proximity to the back 2, and serving to stiffen the back. This strip 3 is provided with holes 4 arranged in rows at the upper end and rows of holes 5 at the lower end, into which holes prongs 6 of retaining staples 7 are passed. The prongs 6 which enter the upper holes 4, are forced downwardly and the prongs which enter the lower holes 5 upwardly between the back 2 and. the re against "displacement; j a

The staples 7- are formed with inforcing strip 3, thus holding the staples gated loop 8, of which the free end-9 isiarranged to pass inwardly into the loop and approXimately in parallelism with the prong. This free end 9 has a yielding en"- gagement with the prong 6 forthe purpose of gripping the material passed therebetween, as shown. in Fig.4., I q

To give the inside of the cover boards'a neat finish, awfly leaf 10, may be pasted or otherwise secured thereto and in such ,posi-- tion as to cover and protect the side'edges of the reinforcing strip 3, as. clearly shown in Fig. 2. I V i For carrying a supply of staples, a pocket or envelop 11 is secured to one of the cover boards 1, as clearly shown in Figs. 1 and 2. I

To place a pamphletwithin the binder, the pamphlet is laid open at the middle upon the binder, as shown in Fig. 3, and the prongs of two staples inserted between the back 2 and the strip 3 and forced toward each other until the loops 8' pass onto the pamphlet, whereupon the yielding end 9 will pinch the pamphlet and strip 3 together and hold the pamphlet tightly within the binder. The leaves of the pamphlet may be turned back and forth, using the prongs as a fulcrum, the loops will also turn with the leaves, thus permittingthe pamphlet to be opened flat at any page.

To accommodate pamphlets ofv various sizes in one binder, the holes 4, 5, are arranged in the strip 3 in parallel rows and spaced apart so that the loops 8 of the staples may be brought in contact with the top and bottom of the pamphet which is to be inserted in the binder. To bind the maximum length pamphlet, the prongs of the staples may be inserted between the back and strip at the upper and lower ends of the strip 3.

Thus it will be seen that pamphlets of various lengths may be bound within a single binder without'displacing or disarranging the retaining element of the ad acent pamphlet or spoiling the uniformity of the binder as a whole, because each pamphlet is dependent upon its own staples to retain it in place.

Furthermore, the pamphlets are retained within the binder without being mutilated, defaced or previously pre ared other than the usual-vertical central old, and any one may be removed from any part of the binder Without disturbing the remaining pamphlets.

What I claim is: y 1.. A pamphlet binder comprising cover boards, a back, a reinforcing strip for said back secured to the inside edges of said "cover'boards in close proximity to the back and having series of holes therein, and retalnlng means for the pamphlet, each of said means having a prong arranged to enter one of said holes and restbetweenthe back and strip, and an elongated loop formed parallel cover boards in close proximity to the back and having series of holes therein, and retaining means for the pamphlet, each of said means having a prong arranged to enter one of-said holes and rest between the back and strip, and an elongated loop adapted to yieldingly engage the pamphlet along its vertical central fold to hold it securely against the reinforcing strip throughout its length.

8. A folded pamphlet binder comprising cover boards, a back, a reinforcing strip for said back secured to the inside edges of said cover boards in close proximity to the back and having a series of holes therein, and re taining means for the pamphlet, each of said means having a prong arranged to enter one of said holes and pass between the back and strip, and an elongated loop formed parallel With said prong, said retaining means adapted to yieldingly engage the pamphlet at the upper and lower ends of its vertical central fold to hold it securely against the reinforcing strip throughout its length.

In testimony, that I claim the foregoing as my invention, I have signed my name this 7th day of August 1917.

GEORGE G. H. FRITZSOHE.
